This application is a continuation-in-part of U.S. patent application Ser. No. 13/087,212, filed Apr. 14, 2011, entitled “Cosmetic Applicator Systems,” a continuation-in-part of U.S. patent application Ser. No. 13/955,817, filed Jul. 31, 2013, entitled “Applicator Assembly,” which claims the benefit of U.S. Provisional Patent Application No. 61/677,861, filed Jul. 31, 2012, and this application also claims the benefit of U.S. Provisional Patent Application No. 62/236,840, filed Oct. 2, 2015, entitled “Computerized Cosmetics Brushes,” all of which are incorporated herein by reference in their entirety.

BACKGROUND

Makeup brush applicators consist of two main components: a handle and brush head (the “brush head”), which are banded bristle hair (the “bristles”) made of either natural or synthetic fibers and configured in such a way as to effectively apply makeup, lotions, serums or creams (the “makeup”) to parts of the body as required by the user (the entire tool is hereinafter referred to as the “makeup brush applicator”). The handles and brush heads are each designed and constructed in different shapes, sizes, colors, finishes and materials for functional and aesthetic reasons. The brush head shapes have been designed to apply specific kinds of makeup using certain techniques, methods or motions. For instance, a foundation brush designed to apply makeup evenly across a larger area, such as an entire face, requires a different shape than a blush brush designed to apply makeup more narrowly to the cheek area of the face.

Since traditional makeup brushes have been manual tools, brush head shape have been designed for manual use only. Brush-head shapes include but are not limited to flat, domed, or sloped straight across from one side to the other. As a manual tool, traditional makeup brush applicators require the user to move the makeup brush applicator with certain sweeping and circular motions or techniques in order to function effectively. These motions cause the bristles to bend and sweep in one direction so to uniformly apply the makeup.

Certain automated makeup brush applicators include a brush head that spins on an axis with the bristles oriented parallel to the axis on the end of the handle. Being automated, this type makeup brush applicator requires a simpler motion and less effort or skill by the user compared with traditional makeup brushes in order to achieve similar results. This type brush head applicator causes multiple forces to act on the bristles as the brush head may be spinning (e.g., rotating about its axis) and moving linear at the same time. Since automated spinning makeup brush applicators have not existed until recently, no brush-head design has even contemplated the impact of the spinning motion of the brush head on the bristles' ability to perform uniformly.

When a traditional brush head design is used for a spinning brush head, the bristles will bend or flare in a sweeping motion, but also in a concentrated revolving motion. The bristles furthest from the center-axis point may bend or flare more because they encounter little-to-no resistance from bristles further away from the center-axis point. Conversely, the bristles closest to the center-axis point will bend or flare the least since they encounter resistance from all of the other bristles of the spinning brush head. Therefore, when using a traditional brush-head design for a spinning brush head, the combination of the banded-bristle density and the revolving motion of the bristles results in the center-area bristles (1) not bending and (2) sticking out further than any other bristles of the brush head. These shortcomings result in a reduction in the overall effectiveness of the brush head, and potential discomfort for the user since the center bristles exert force on the user's skin since they do not bend or flare.

Various embodiments of the present brush designs recognize and address the foregoing considerations, and others, of prior art brush designs and methods of use.

DETAILED DESCRIPTION

Various embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

Overview

In automated makeup applicators (e.g., motorized) where a rotatable makeup brush head is coupled to a motorized applicator handle, the makeup brush head spins causing the bristles to flare radially outward from the axis of rotation. Depending on the length, rigidity of the bristles, the density of the bristles, the speed and torque of the motor spinning the brush head, and the position of the bristles, the bristles may flare out or bend differently. Using a traditional brush head design (e.g., bristle configuration), each bristle bends or flares differently depending on the position of the bristle with respect to every other bristle. Outer bristles will flare radially outward from the axis of rotation of the brush head while central bristles may not bend or flare at all. This occurs because bristles closer to the center rotate about a smaller radius of curvature than those bristles positioned further away from the axis of rotation. Moreover, bristles located closer to the axis of rotation are prevented from bending or flaring due to the multitude of bristles positioned further away from the axis of rotation. As a result, the central bristles may not bend or flare at all and remain straight and rigid forming a point that protrudes beyond the plane that intersects the ends of the outer bristles, thereby causing discomfort and uneven touching on the surface of the user's skin.

The present brush designs eliminate the short comings of prior brush designs by creating a makeup brush where the central bristles are shorter than at least a portion of the outer surrounding bristles. According to various embodiments, a brush head design is disclosed for use with a spinning brush head attached to an automated (e.g., motorized) makeup brush applicator. In particular embodiments, the brush head comprises a generally cylindrical body having a first end configured to releasably attach to the motorized handle and a second end that defines a recess therein that is configured to receive a plurality of bristles. In various embodiments, the plurality of bristles is configured such that the outer bristles are of a longer length than the inner bristles thereby forming a concave surface across the free ends of the bristles. In this way, when the brush head is spinning relative to the motorized handle, the outer bristles can flare or bend with respect to the central bristles (e.g., the bristles closer to the axis of rotation) so that the bristle ends during rotation conform to the surface to which a cosmetic is being applied.

In various embodiments where the bristles ends define a generally circular shape, the furthest-most exterior bristles of the brush (e.g., those furthest from the axis of rotation) appear as a certain length as they protrude from the makeup brush head body while the bristles closer to the axis of rotation appear as a different length (e.g., a shorter length the closer you get to the axis of rotation) thereby creating an angle or slope down to the center (e.g., the axis of rotation of the brush. That is, the surface defined by the free ends of the bristles is sloped downward toward the axis of rotation in a straight slant, along a radius of curvature or a combination of both. In various embodiments, the angle of slope may be between about 5 degrees to about 25 degrees in some embodiments, between about 5 to 20 degrees in other embodiments, and between about 8 to 18 degrees in preferred embodiments. For makeup brushes whose bristle free ends generally define a convex surface, the pressure exerted by the central bristles (due to the inability for the central bristles to bend of flare) may be minimized or eliminated by creating a concave central portion defined by the free ends of the central most bristles (e.g., those bristles at and around the axis of rotation) of the makeup brush thereby forming a recess about the axis of rotation.

In various embodiments, the concave surface defined by the free ends of the bristle may be formed using various methods. In a first method, bristles positioned radially closer to the axis of rotation may be formed of a first length while bristles positioned radially further from the axis of rotation may be formed of a second length. In this way, the free bristle ends define a recessed portion that surrounds the axis of rotation. In a second method, all bristles may be of a first length. A plurality of bristles may be inserted into a cup like structure where the bottom surface of the cup defines the shape of the surface to be defined by the free bristle ends. The ends of the bristles to be bound may be tapped or urged into the cup so that the free ends of the bristles conform to the shape defined by the bottom surface of the cup. The ends of the bristles to be bound and mounted into the makeup brush head may be surrounded by a metal band to maintain the cross-sectional shape of the plurality of bristles. That is, the bristles are generally displaced with respect to one another so that the banded end of the bristles takes on the general shape of the bottom surface of the cup. Once all of the bristles are seated properly in the cup, the band may be crimped or fastened around the banded end of the bristles to secure the bristles into a bundle that retains the shape defined by the free ends of the bristles. Once the band is crimped or fastened, the banded bristled may be removed from the cup and a portion of the banded end of the bristles may be cut thereby creating a substantially flat surface defined by the cut banded ends of the bristles. The banded end of the bristles may then be mounted into the makeup brush head and secured in place using any suitable fastener (e.g., glue, hot glue, adhesive, press-fit, etc.).

In still other embodiments, the makeup brush applicator may be formed in two parts. In some embodiments, the makeup brush body may be formed from a first ring shaped cup body that is mounted to but axially moveable with respect to a second central generally cylindrical shaped cup body. In these embodiments, a first plurality of bristles is mounted in the first ring shaped cup body and a second plurality of bristles is mounted in the second central generally cylindrical shaped cup body. Because the first ring shaped cup body is moveable with respect to the second central generally cylindrical shaped cup body, when the first ring shaped cup body is moved axially forward with respect to the second central generally cylindrical shaped cup body, the bristle ends of the first plurality of bristle are axially forward of the bristles ends of the second plurality of bristle (e.g., or the bristle ends of the second plurality of bristles are recessed from the bristle ends of the first plurality of bristles thereby forming a concave surface (e.g., linearly sloped or sloped along a curve) defined by the free ends of the first plurality and second plurality of bristle.

Rotatable makeup brush heads for use with an elongated motorized brush support are generally formed from a brush cup comprising a generally cylindrical body having a first end adapted to rotatably couple to the motorized brush support and a second end that defines a recess therein that is configured to receive the plurality of bristles. In various embodiments, the free ends of the bristles are what define the application surface of the brush and the opposite ends of the bristles are typically bound to together using one or more of a band and/or glue. When the banded ends of the bristles are inserted into the recessed second ends of the brush cup, it is important that the center of the banded bristles align with the axis of rotation of the brush cup to minimize and/or eliminate wobble of the brush cup as it is spinning with respect to the motorized brush support. Centering the bound bristles in the brush cup may be accomplished by one or more of the following: (1) positioning the banded bristles in the center of the recess; (2) facilitating even distribution of glue within the brush cup; and (3) allowing for more glue to fill the brush cup well so as to provide extra weight. The above is accomplished by forming a plurality of ridges on the walls that define the recess in the second end of the generally cylindrical body of the brush cup that extend radially inward toward the axis of rotation of the brush cup. In this way, the ridges help to guide the banded bristles into the correct position and provide for an equal spacing between the walls of the recess and the banded bristles.

In various embodiments, three ridges may be formed that extend from the walls of the recess radially inward. The three recess guided the banded bundle of bristles into the recess while aligning the center of the banded bristles with the axis of rotation of the brush cup. In carious embodiments, the ridges may be between 0.2-0.4 mm in depth and may form a press-fit (e.g., friction fit) between the ridges and the bundle of bristles. In various embodiments, the depth of each ridge may be smaller at the mouth of the recess to allow the bundle of bristles to easily be guided into the brush cup. In other embodiments, additional ridges may be formed at equal spacing along the inner circumference of the recess to increase the accuracy of centering of the bundle of bristles with respect to the axis of rotation and to provide additional points of contact against the band holding the bundle of bristles together.

Exemplary Makeup Application Kit

As shown in FIG. 1A, a makeup application kit according to various embodiments includes a handheld applicator assembly 100 that includes a motorized applicator support (e.g., a motorized brush support 102) and an applicator 200 (e.g., a makeup brush). In particular embodiments, the applicator 200 is mounted adjacent (e.g., to) the end of the applicator support 102, and the motorized applicator support 102 is adapted to (e.g., configured to) selectively rotate the applicator 200 at least substantially about the applicator's 200 central axis 116 (e.g., axis of rotation). This allows the applicator 200 to move in a smooth, rotational motion while the user is applying makeup or other cosmetics of any suitable kind to the skin. The applicator assembly 100 is particularly useful in allowing users to uniformly apply makeup, and other cosmetics, to specific portions of their face. During this process, the applicator assembly 100 may be used to blend (e.g., substantially evenly blend) multiple cosmetics together. However, the applicator 100 may also be used to apply substances to other portions of the user's body. For example, the applicator 100 may be used to uniformly apply suntan lotion, sunscreen, bronzer, or any other cosmetic or medical preparation (or any other suitable substance) to a user's arms, legs, feet, neck, or other body parts.

A handheld applicator assembly system, according to various embodiments, includes a set of detachable and interchangeable cosmetic brushes for applying a cosmetic to a surface area of the user's body, such as their face. A cosmetic for a surface area such as the face may include any of a variety of different compounds, such as liquids, creams, gels, powders, and the like. These compounds may be tinted with color, suffused with decorative additives such as glitter or colored powder, and/or infused with nourishing or therapeutic compounds such as sunscreen.

Each of the cosmetic brushes may be customized in size, shape, and stiffness to facilitate the application and blending of a cosmetic across one or more specified zones on the user's body. For example, a zone near the eyes may benefit from a cosmetic brush that is relatively small in size, rounded in shape, and soft in stiffness. In particular embodiments, each of the cosmetic brushes is adapted to be selectively attached to, and detached from, the motorized rotating brush support discussed above. In particular embodiments, this may allow users to use a single base device in conjunction with multiple specialized brushes and cosmetics to apply the appropriate makeup to each individual zone of their face (or other body part) using a makeup, brush, and application technique that have each been customized and/or specifically selected for that particular zone.

In particular embodiments, the rotating brush support is a motorized handheld tool having a handle, a motor, and a head assembly that includes a coupling assembly for releasably receiving any of the cosmetic brushes. The motor may include a drive shaft connected to the head assembly for rotating the attached brush during use. The system may also be used without power, as a manual brush.

In various embodiments, the makeup application kit includes detailed instructions (e.g., in the form of electronic or printed materials, computer software, and/or one or more videos) for instructing a user how to use the kit's various components (for example, using the techniques described below).

Exemplary Handheld Applicator Assembly

As shown in FIG. 1A, the handheld applicator assembly 100 includes a motorized applicator support (e.g., a motorized brush support 102) and an applicator 200 (e.g., a makeup brush). In particular embodiments, the applicator 200 is mounted adjacent (e.g., to) the end of the applicator support 102 and the motorized applicator support 102 is adapted to selectively rotate the applicator 200 at least substantially about the applicator's central axis 116.

In particular embodiments, the motorized applicator support 102 comprises a handle 104 and a head assembly 112 for receiving an applicator 200. The handle 104 has a proximal end 106 and a distal end 108. The distal end 108 is closer to the user when the applicator assembly 100 is in use. The handle 104 may include an interior chamber (e.g. a cavity). The handle 104 may be elongated in shape, as shown, extending lengthwise along a central axis 116 between the proximal end 106 and the head assembly 112. In various embodiments, the handle 104 may be any size and shape that is comfortable to grip and otherwise suitable for grasping and maneuvering the applicator assembly 100. The handheld applicator assembly 100 may be sized and shaped to fit easily into a carrying case, purse or other bag for portability. The various components of the handheld applicator assembly 100 may be optimized toward a minimum overall size and weight to further facilitate portability.

The head assembly 112 may be configured to receive the applicator 200. As shown, the applicator 200 mounted on the handheld applicator assembly 100 may be a cosmetic brush. In particular embodiments, the applicator 100 may be held and manipulated by a user in order to use the cosmetic brush to distribute a cosmetic across a selected surface area such as the face.

Applicator Cup

Referring to FIGS. 1B1-1C4, the applicator 200 (FIG. 1A) may include a variety of different types of applicator cups 118 or 118A for mounting the bristles. The applicator cup 118, 118A allows the applicator 200 to connect to the applicator assembly 100, as described further below. As shown in these figures, the applicator cup 118, 118A may comprise a substantially cylindrical (e.g., cylindrical), at least partially hollow, cup body portion 110 f, 110A that includes a side wall 115, 115A, a top face 120, 120A, and a bottom face 130, 130A. In particular embodiments, the cup body portion 110, 110A may have a substantially circular (e.g., circular) cross section. The cup body portion 110, 110A may define an applicator-receiving recess 140, 140A adjacent (e.g., extending through) the cup's top face 120, 120A and an attachment recess or stem adjacent (e.g., extending through) the cup's bottom face 130, 130A. In some embodiments, the applicator cup 118 or 118A may include at least one finger grip disposed adjacent the cup's upper portion. The finger grip may be, for example, a protrusion (e.g., 325 of FIGS. 5A-5C, and 5E) that extends outwardly from the outer surface 115, 115A of the cup body portion 110, 110A. In various embodiments, the finger grip may have any width and height suitable for allowing a user to grip the applicator cup's body portion 110, 110A. In some embodiments, the finger grip may extend partially along the circumference of the cup's outer surface 115, 115A or substantially along the entire circumference of the cup's outer surface.

Cup

Still referring to FIGS. 1B1-1C4, body portion 110, 110A of the applicator cup 200 may be substantially cylindrical (e.g., cylindrical) with a diameter between, for example, about 20 mm and about 40 mm. In particular embodiments, the body portion 110, 110A may have a diameter of about 29.4 mm. In various embodiments, the body portion 110, 110A may have a height between about 20 mm and about 40 mm. In particular embodiments, the body portion 110, 110A has a height of 31.8 mm. In the embodiments shown in FIGS. 1B1-1C4, the body portion 110, 110A defines the top 120, 120A and bottom face 130, 130A and defines a beveled edge on the outer circumference of the edge of the bottom face 130, 130A. In other embodiments, the body portion 110, 110A may define any other suitable edge (e.g., round or square) on the outer circumference of the edge of the bottom face 130, 130A.

Applicator-Receiving Recess

In the embodiments shown in FIGS. 1B1-1C4, the body portion 110, 110A defines an applicator-receiving recess 140, 140A that is substantially centered (e.g., centered) relative to the cup's top face 120 and the axis of rotation 116. In the embodiments shown in these figures, the applicator-receiving recess 140, 140A is substantially cylindrical (e.g., cylindrical) and has a diameter that is between about 15 mm and 39 mm. In particular embodiments, the applicator-receiving recess 140, 140A have a diameter of about 28.1 mm. In certain embodiments, the applicator-receiving recess 140, 140A has a diameter that is about 0.5 mm less than the body portion's 110, 110A overall diameter. In the embodiments shown in these figures, the applicator-receiving recess 140, 140A is between about 18 mm and 39 mm deep. In particular embodiments, the applicator-receiving recess 140, 140A is about 24 mm deep. In other embodiments, the applicator-receiving recess 140, 140A may be any depth suitable for housing an applicator.

In various embodiments, the body portion 110, 110A may be adapted to maintain an applicator (e.g., a plurality of bristles, a pad, etc.) at least substantially within (e.g., within) the applicator-receiving recess 140, 140A. In various embodiments, the applicator may be substantially permanently (e.g., permanently) coupled in the applicator-receiving recess 140, 140A via any suitable means (e.g., such as adhesive, glue, bond, screws, bolts, press-fit, friction fit, etc.) so that the applicator is centered about the axis of rotation 116 to prevent an unbalance of the applicator cup 118, 118A with respect to the applicator support 102 when the applicator 200 is rotating. In other embodiments, the applicator may be interchangeably coupled to the applicator-receiving recess 140, 140A via any suitable means (e.g., non-permanent adhesive, Velcro®, magnet, etc.).

The applicator may, according to various embodiments, comprise a brush, sponge, or any other suitable applicator for applying either a liquid or a powder substance (e.g., such as cosmetics, makeup, lotion, sunblock, sunscreen, moisturizer, foundation, concealer, eye shadow, blush, bronzer, cream, or any other appropriate substance). In various embodiments, an applicator may be adapted for applying substances in a plurality of forms (e.g., liquid, powder, or any other suitable form). In particular embodiments, the applicator is adapted to apply cosmetics or lotions while rotating. The applicator may, for example, be adapted to substantially maintain its shape and structure after repeated use.

Referring to FIGS. 1D1-1E2, the applicator may include a brush 170, 170A, 170B, 170C comprising bristles 172, 172A, 172B, 172C of any suitable length (e.g., between about 10 mm and about 80 mm). The bristles may be made of any suitable material (e.g., natural or synthetic material). In various embodiments, the bristles 172, 172A, 172B, 172C may be coupled to the applicator-receiving recess 140, 140A via any suitable method. In various embodiments, the bristles 172, 172A, 172B, 172C may be configured so that the bristles the furthest radially outward from the axis of rotation 116 appear to be longer than the bristles closet to the axis of rotation 116. In this configuration, the free ends of the bristles 172, 172A, 172B, 172C define a recessed surface.

Bristle Configuration

In the bristle configuration 170 shown in FIG. 1D1, the free ends of the bristles 172 define a generally conical shaped recess 173 with a surface that slopes about 1 degree from the outer bristles to the center bristles. Moreover, in the bristle configuration 170A shown in FIG. 1D2, the free ends of the bristles 172A define a generally conical shaped recess 173A with a surface that slopes about 12 degree from the outer bristles to the center bristles. It should be understood that in various embodiments, the bristles may slope from about 5 degrees to about 25 degrees, in other embodiments the bristles may slope from about 5 to 20 degrees and in particular embodiments the bristles may slope from about 8 to 18 degrees.

Referring to FIGS. 1E1-1E2, for makeup brushes whose free ends of the bristles 172B, 172C generally define a convex surface (e.g. a domed shape surface), the pressure exerted by the central bristles (due to the inability for the central bristles to bend of flare) may be minimized or eliminated by creating a concave central portion 173B, 173C defined by the free ends of the central most bristles (e.g., those bristles at and around the axis of rotation 116) of the makeup brush thereby forming a recess about the axis of rotation 116. The bottom of the concave central portion 173B, 173C may range between about 0.5 mm to about 1 mm from the highest most fee ends of the surrounding bristles. Similar to the concave bristle design, domed recess design prevents the center of the brush head from protruding further than the outer bristles while the brush head is spinning in order to decrease any discomfort to the user from the center bristles, which are held in place by the outer bristles and thus do not fan out like the outer bristles when the brush head is spinning.

Methods of Forming the Brush Head

In order to form the particular surfaces defined by the free ends of the bristles, in various embodiments, a bundle of bristles having generally the same length may be bundled together. In some embodiments, the ends of the bristles opposite the free ends may be banded together using a band formed from any suitable material such as paper, metal, polymer, rubber etc. The bundle of bristles are then inserted with the free ends first into a brush head shaping cup that has a bottom surface configured to form the shape of the surface defined by the free ends of the bristles.

For example, if the free ends are to form a surface as shown in FIGS. 1D1-1D2, the bottom surface of the cup is convex so that as the free ends of the bundle of bristles are inserted into the cup, the bottom surface of the cup causes the central bristles to move axial away from the outer bristles such that the banded ends of the bristles conform to the bottom surface of the cup (e.g., the banded ends of the bristles define a convex shaped surface. In order to ensure that all of the bristles are properly aligned, the band holding the bundle of bristles may be loosened or removed to allow all of the bristles to properly align to the bottom surface of the cup. Additionally, the cup and/or the banded end of the bristles may be tapped or jarred to cause the bristles to properly seat against the bottom surface of the cup. Once the seating process is completed, the band may be tightened, crimped, glued and/or fastened in any other suitable manner to ensure that the banded end of the bristles are tightly secured so that no bristles move when the bundle of bristles are removed from the cup. Once the banded and secured bundle of bristles is removed, the banded ends of the bristles may be cut so that the banded end of the bristles are even or left as is.

In other embodiments, bristles of varying lengths may be placed in a bristle-forming cup that has a flat receiving recess with a flat base. In still other embodiments, bristles of the same length may be banded together and secured at one end. Once the bundle of bristles has been secured, the free ends of the bristles may be cut into any suitable shape. It should be understood that the free ends of the bristles may be made to conform to any suitable shape where the central bristles are recessed relative to at least some of the surrounding bristles. That is, a first plurality of bristles surrounds a second plurality of bristles. The free ends of at least some of the second plurality of bristles (for example, a first group of the second plurality of bristles) are recessed with respect to the free ends of at least some of the first plurality of bristles (for example, a second group of the first plurality of bristles). The result is a plurality of bristles where the free ends of the bristles define a surface that is generally concave in shape where at least a portion of the walls defining the recess are linear and/or curved.

Referring to FIG. 1F, a generally cylindrical body portion 110 is shown having a recess 140 that is configured to receive the bundled bristles. As discussed above, once the bundle of bristles is banded it is important to center the banded bristles when inserting the banded end of the bristles into the applicator receiving recess 140 such that the center of the banded bristles aligns with the axis of rotation of the cylindrical body portion 110. In various embodiments, the applicator-receiving recess 140 may include one or more ridges 160 that run vertically from the top of the opening 162 of the applicator-receiving recess 140 to the cups' bottom surface 164.

In particular embodiments, the applicator-receiving recess 140 may include 3 or more ridges 160 as shown equally spaced about the inner circumference. The ridges 160 may radially extend inward from the inner wall 161 of the applicator-receiving recess 140 approximately 0.2-0.4 mm in depth in order to keep the banded bristles centered in the applicator-receiving recess 140. In particular embodiments, the depth of the ridges may gradually get larger as the ridges get closer to the cup's bottom surface 164. This makes it easier to insert the banded end of the bristle bundle into the cup. In addition, as the banded end of the bristles is inserted, the ridges 140 may be configured to cause a friction fit to exist between the band and the ridges 160. The ridges 160 may further be used to provide an even amount of space between the band and the inner wall 164 of the applicator-receiving recess 140 so that when glue is introduced, there will be a uniform amount of glue around the banded bristles between the band and the walls of the recess. Having a uniform amount of glue helps to minimize or eliminate wobble when the applicator 200 is rotated on the motorized handle 102.

Makeup Brush with Selectively Configurable Bristle Configuration

Turning now to FIGS. 1G-1I, in various embodiments, the makeup brush may be configured to work with various replaceable brush heads that are adapted to be selectively coupled to the makeup brush. In various embodiments, such as the embodiment shown in FIGS. 1G-1I, the brush head 500 may comprise a first body 505 (e.g., a generally cylindrical body having a firs recess) that is configured on one end to releasably couple to the motor contained in the makeup brush either directly or through one or more other mechanical connections such that rotation of the motor causes the first body 505 to rotate with respect to the makeup brush's handle. In various embodiments, the first body 505 may be substantially cylindrical and comprise a first plurality of first, outwardly extending bristles. The first body 505 may be surrounded by a second body 510 (e.g., a generally ring shaped body) that is axially moveable with respect to the first body in a direction parallel to the axis of rotation of the first body 505. In some embodiments, the second body 510 may be formed in the shape of a ring with an inner opening that is slightly larger than the diameter of the first body 505. In various embodiments, the second body 510 may contain a second plurality of outwardly extending second bristles. In particular embodiments, the second body 510 may be movable between one of at least three positions, which are shown, respectively, in FIGS. 1G-1I. In a first position, shown in FIG. 1G, the free ends of the first plurality of first bristles of the first body 505 are substantially coplanar with the free ends of the second plurality of second bristles of the second body 510. In a second position, shown in FIG. 1I, the ends of the first plurality of first bristles of the first body 505 are recessed from the free ends of the second plurality of second bristles of the second body 510. In the third position, shown in FIG. 1H, the free ends of the second plurality of second bristles of the second body 510 are recessed from the free ends of the first plurality of first bristles of the first body 505. In this way, the width of the bristles that engage with the user's skin may be changed. Moreover, the configuration shown in FIG. 1I also alleviates undue pressure exerted by the center bristles as discussed above. In order to secure the second body 510 in one of the first, second or third positions with respect to the first body 505, a spring loaded ball, pin or other locking mechanism may be formed in one of the first and second bodies 505, 510 and a detent (a recess, a blind bore, etc.) may be formed in the other one of the first and second bodies 505, 510 so as to axially and rotationally retain the first body 505 to the second body 510.

Attachment Recess

Returning to FIGS. 1B1-1C4, the cup's body portion 110 may define one or more attachment mechanisms (e.g., bottom surface 130 or attachment recesses 150A) that is suitable for use in attaching the applicator cup 110 to the handle 102 when the body portion 110 is attached to the handle. The handle may, for example, be a motorized handle or any other handle suitable for use in applying cosmetics. Referring briefly to FIGS. 5A-5G, exemplary motorized handles 400 and 450 are shown.

As may be understood from FIGS. 1B1-1C4, the attachment mechanism-bottom portion 130 or attachment recess 150A may be sized to either be received in a coupling recess or to receive a corresponding portion (e.g., a rotating portion) of a motorized handle when the applicator cup 118, 118A is attached to the motorized handle. In various embodiments, the engagement between the coupling recess 340 (FIG. 5F) of the motorized handle and the applicator cup 118, 118A causes the applicator cup 118 to rotate when the motorized handle's rotating portion rotates. In particular embodiments, the applicator cup 118, 118A may define an attachment recess that is between about 2 mm deep and about 14 mm deep.

No Attachment Recess

In particular embodiments and referring to FIGS. 1B1-1B2, the applicator cup 110 may define no attachment recess. In such embodiments, the applicator cup 110 may be adapted to be attached to a handle via a press-fit. Moreover, in various embodiments, the cross-section of the bottom surface may be polygonal to provide a secure connection between the bottom surface 130 and the coupling portion of the handle.

Multi-Sided Recess

The brush cup 110A shown in FIGS. 1C1-1C4 defines an attachment recess 150A that is substantially centered (e.g., centered) adjacent the cup's axis of rotation 116, and that has a profile that is substantially polygonal (e.g., square, hexagonal, octagonal, etc). In this embodiment, the profile of the attachment recess is that of a shape with any suitable number of sides (e.g., triangular, square, pentagonal, hexagonal, heptagonal, etc.). The attachment recess 150A is configured to receive a rotatable coupling mechanism that allows the brush cup 110A to rotate with respect to the motorized handle 102.

Alternative Attachment Recesses

It should be understood that the brush cup may be configured to attach to the motorized handle using any suitable attachment mechanism such as a cross shaped recess, a substantially S-shaped (e.g., S-shaped) recess, a figure eight recess, a multi-hole recess, etc. In addition to recesses, the attachment mechanism may also include an attachment shaft rather than an attachment recess. The attachment shaft may have a profile that is substantially polygonal (e.g., polygonal) and that extends about 7 mm from the cup's bottom surface. In other embodiments, the attachment shaft may extend between about 3 mm and about 15 mm from the cup's bottom surface. In various embodiments, the attachment shaft may have any other suitable profile. For example, the attachment shaft may have a profile that is similar to any of the profiles of the attachment recesses described above (e.g., figure eight, multi-sided, cross, or serpentine).

Motor, Power Source, Drive Shaft

Referring specifically to FIGS. 1A and 5 A-5G, the handheld applicator assembly 100, 400, 450 may include a motor 113 and a power source 114, which may be located within a chamber inside the handle 104. The motor 113 may comprise any of a variety of different motor assemblies such as a typical mechanical or electromechanical motor, a cam assembly, a magnetic assembly, a sonic or ultrasonic mechanism, a vibrating motor, or any of a variety of motor assemblies known to those skilled in the art. The power source may comprise one or more cells such a cosmetic brush single-use or rechargeable batteries or, optionally, may include a cord for coupling to an electrical outlet. In one embodiment, at least a portion of the power source is mounted within the handle 104 while a recharging source is located outside the handle. The motor 113 may be activated by a switch 111 (FIG. 5) mounted on the handle 104.

The motor 113 may include a drive shaft 109 extending lengthwise toward the distal end 108 of the handle 104, where the shaft connects to the head assembly 112 (FIG. 1A). The motor 113 may extend lengthwise along an axis that is substantially parallel to the central axis 116 of the handle 104. The motor 113 and drive shaft may be configured to impart movement to the applicator 200. In some embodiments, the movement may be vertical with respect to the handle 104 or horizontal with respect to the handle 104. In other embodiments, the movement may be rotational. The rotation may be substantially coaxial relative to the drive shaft. Alternatively, the rotation may be eccentric relative to the drive shaft, and the angle of the applicator 200 relative to the drive shaft and/or handle 104 may be selectively adjustable between, for example, an angle of about 0 and an angle of about 90 degrees to give the user the ability to personalize their brush for ease of use. The movement imparted to the applicator 200 may also include some amount of vibration, oscillation, translation in any direction, and combinations thereof. Any variety and combinations of movements may be employed in order to evenly and precisely distribute a cosmetic over a surface area of the body in a desired manner. In use, the motions of the user's hand may also impart movement to the applicator 200 in various directions. Also, the handheld applicator assembly 100 in some embodiments may be operated without use of the motor 113 or the power source, as a manual brush.

The motor 113, power source 114, switch 111, and drive shaft 109, in some embodiments, may be configured to drive the applicator 200 primarily in rotation about the applicator's central axis 116, or about any other suitable axis. The motor 113 may be configured to rotate the applicator 200 at a single constant speed, at a variety of intermediate speeds, or at variable speeds. For example, the motor 113 may be configured to rotate the applicator 200 at a relatively slower speed when the applicator 100 is being used on a relatively delicate or fragile surface. A higher intermediate speed may be used when the applicator 100 is being used on a relatively robust or sturdy surface. In this aspect, the switch 111 controlling the motor 113 may include a variety of intermediate speed settings or, in some embodiments, may include a slide or other element configured to operate the motor 113 at variable speeds. The motor 113 may also be configured to heat or cool the applicator in order to apply various types of cosmetics.

In some embodiments, the motor 113 may vary the rotating speed of the applicator 200 based on a force exerted on the handheld applicator assembly 100 by the applicator 200 when the applicator presses against a surface. In this aspect, the more the user presses the applicator 200 against a particular surface, the more the motor 113 will vary the rotating speed of the applicator 200. For example, a particular user might use a relatively vigorous force to press the applicator 200 toward and into relatively minute features of the face, such as pores, furrows, creases, wrinkles, and the like. In some embodiments, the motor 113 may vary the rotating speed of the applicator 200 based on the force exerted on a switch or other component located on the handheld applicator assembly 100. In this aspect, as the user pushes against or slides the switch or other component, the motor 113 will vary the rotating speed of the applicator 200.

In various embodiments, the handheld applicator assembly 100 may include a computerized driver assembly that is programmed or otherwise configured to drive the applicator 200 through a series of predetermined rotational routines. In this aspect, the motor 113 may be automatically controlled by a computerized driver assembly in order to provide guidance to the user.

Detachable Applicators, Coupling Assembly

Referring specifically to FIGS. 1A and 2A-2H, as described above, the handheld applicator assembly 100 in some embodiments includes a head assembly 112 for receiving an applicator 200. The applicator 200 may be permanently or releasably attached to a coupling assembly 132. In some embodiments, the coupling assembly 132 may be configured to releasably receive an applicator 200, such that a user can manually attach and remove any of a variety of detachable applicators interchangeably such as applicators 220. The applicator 200 in some embodiments may include any of a variety of tools suitable for evenly and precisely distributing a cosmetic over a surface area of the body with a desired degree of control. For example, the applicator 200 may be a soft disk, a sponge, a semi-porous pad, a brush, a roller, or the like, and any combinations thereof. The applicator 200 may be a single unit or it may be comprised of multiple components.

The coupling assembly 132 in some embodiments may be a bayonet-type assembly, for example, which includes a male element such as a cylinder with one or more radial pins and a female element such as a hollow cylinder with matching L-shaped slots and an internal spring that is biased to push against the male element and thereby keep the pins engaged with the slots. Bayonet mounts are sometimes used for camera lenses and automotive lamps. A bayonet mount may facilitate precise alignment, for example, between the head assembly 112 and the applicator 200. The coupling assembly 132 may be any kind of connector or fastening mechanism, such as a screw-threaded mount, a bayonet mount, a keyhole mount, a channel mount, a friction fit between mating parts, or the like. Any of a variety of coupling assemblies known to those skilled in the art may be used. In some embodiments, the coupling assembly 132 may be configured to cushion or otherwise absorb the vibration and energy from the applicator 200 during use.

Exemplary Applicator System

Still referring to FIGS. 2A-2H, an applicator system 10, as illustrated in FIGS. 2A-2H, may include a motorized brush support 102 and a set of cosmetic brushes 220 for applying a cosmetic to a surface area such as the face. The motorized brush support 100, as shown, includes a base portion (in this case, a handle 102), a head assembly 112, and a coupling assembly 132. The coupling assembly 132 may extend away from the head assembly 112, as shown, or it may be integrated within the head assembly 112. In some embodiments, each of the cosmetic brushes 220 may include a connector 222A-222G for attaching to or otherwise engaging with the coupling assembly 132. The connector 222A-222G may extend below the base of a brush, as shown, or it may be integrated within the base of the brush. The connector 222A-222G may include any type of connector or fastening mechanism that fits or otherwise engages with the coupling assembly 132, as described above in reference to FIGS. 1B1-1C4. Any of a variety of combinations of connectors 222A-222G and coupling assemblies 132 known to those skilled in the art may be used.

Any of a variety of cosmetic brushes (such as one or more specialty makeup brushes) may be collected in a set 220 for use with any particular application. In an exemplary embodiment, the set of cosmetic brushes 220, as illustrated, may include one or more of the following brush types: a Liquidator Brush 220A, a Powder Foundation Brush 220B, an Under-Eye Concealer Brush 220C, an Upper Eyelid Shadow Brush 220D, a Blush Blaster Brush 220E, a Disco Shine Brush 220F, and a Bronzer Brush 220G.

The Liquidator Brush 220A may be used to apply and distribute a liquid or cream foundation. The Powder Foundation Brush 220B may be used to apply and distribute a powder foundation or base. The Under-Eye Concealer Brush 220C may be used to apply and distribute a concealer compound under the eyes and other areas, as desired. The Upper Eyelid Shadow Brush 220D may be used to apply and distribute a shadow compound to the upper eyelids. The Blush Blaster Brush 220E may be used to apply and distribute a blush compound to the “S zone” or cheeks and other areas, as desired. The Disco Shine Brush 220F may be used to apply and distribute a decorative compound such as a colored powder or glitter to any area. The Bronzer Brush 220G may be used to apply and distribute a bronzing compound to any area. In use, any of the set of brushes 220 may be used to apply, distribute and blend any of these compounds to any area of the face and/or body.

The cosmetic brushes in a set 220 may include any number of different brush types. A brush may include a base, a collection of bristles, and a ferrule or other component for holding the bristles to the base. The bristles may be made of natural animal hair, synthetic fibers, or a blend. The base of the brush, in some embodiments, may be made of different materials, in various colors. The brush may include one or more words or indicia correlated to a particular manufacturer, product name, trademark, business or social cause. The set of brushes 220 may be color coded or otherwise grouped by a visible feature that indicates to the user each brush's intended use and/or its association with a particular set of brushes.

Each cosmetic brush may be characterized by its particular features; for example, its overall size and shape, the shape of its base, the ferrule type, the bristle composition (natural, synthetic or blend, for example), the bristle length, the bristle color, the shape of each bristle end (rounded or blunt, smooth or rough, for example), the overall shape made by all the bristles together (fan-shaped, cone-shaped, flat, rounded, pointed, and the like), the bristle spacing and density (measured, for example, in bristles per square inch) and the bristle stiffness (from rigid bristles like a toothbrush, to bristles as limp as cotton thread). For example, in the context of face makeup, a first cosmetic brush (such as The Liquidator Brush 220A illustrated in FIG. 2) may be relatively large in size, flat across the end of the bristles, and relatively rigid in stiffness. A second cosmetic brush (such as The Upper Eyelid Shadow Brush 220D) may be relatively small in size, rounded in shape across the end, and softer in stiffness.

Makeup Brush with Concave Application Surface

In various embodiments described above, the makeup brush head may include a bristle arrangement in which the free ends of the bristles are not substantially coplanar, but, rather are in a substantially concave (or other) arrangement in which the distal ends of the centrally-situated bristles are recessed relative to the free ends of the bristles that are disposed radially outward from the axis of rotation. This may, for example, allow for a makeup brush head that applies substantially even pressure to a body surface when the brush head is being used to apply makeup to the body surface as the brush head is being rotated by the makeup brush's motor. This may also allow, for example, a user to deposit makeup directly into the concave application surface in order to apply a greater amount of makeup to the user's face and/or body. For example, the concave application surface may be beneficial in applying body paint to a person's entire body because it allows the user to cover a greater area of the person's body without reloading the makeup brush with makeup.

In particular embodiments, the recess formed by the respective ends of brush head's bristles may be, for example, substantially in the shape of a cone, a dome, or any other suitable shape.

Systematic Correlation of Compound, Zone, and Brush

Referring again to FIGS. 2A-2H, 3 and 4A-4H, the applicator system 10, in some embodiments, may include a handheld applicator assembly 100, a plurality of different cosmetics, instructions that include a depiction of a surface area 300 of the body divided into a number of different zones (as shown in FIG. 3), and a set of cosmetic brushes 220. The cosmetic brushes may be customized in size, shape, stiffness, and/or other parameters to facilitate the application and blending of one or more of the different cosmetics into one or more of the zones of the surface area. In this respect, for example, the brush types may be correlated to both the cosmetic compound and the corresponding zone of the human face. The applicator system 10 in some embodiments may include a makeup application system and method which provides to the user a systematic correlation between each particular cosmetic within the applicator system and: (1) each zone within a specified surface area 300 to receive the particular cosmetic; and (2) a particular cosmetic brush 220 (e.g., selected from the provided set of cosmetic brushes) that is to be used in applying the cosmetic to each particular zone within the specified surface area 300.

The plurality of different cosmetics may include any number and variety of different compounds. For example, as described above in the context of face makeup, a first compound may be a liquid or cream foundation; a second compound may be a powder foundation or base; a third compound may be an under-eye concealer; a fourth compound may be an eyelid shadow; a fifth compound may be a blush; a sixth compound may be a decorative compound such as a colored powder or glitter; a seventh compound may be a bronzer; and so forth.

A surface area 300 such as the face, as illustrated in FIG. 3, may be characterized as including one or more zones, such as: (1) a “T Zone” 320 that includes the forehead and nose; (2) an upper eyelid zone 310D; (3) an under-eye zone 310C; (4) an “S Zone” 310E that includes the cheeks; (5) an “O Zone” 330 around the mouth; and (6) other peripheral zones such as the neck, the ears, the hairline, and the like.

The cosmetic brushes in a set 220 may include any number of different brush types. As described above, each cosmetic brush may be characterized by its particular features such as overall size and shape, bristle type, and stiffness. Each brush in a set of cosmetic brushes 220 may be customized in size, shape, stiffness, material, and other parameters to facilitate the application and blending of a selected cosmetic compound to a particular zone to receive the makeup. In some embodiments, for example, a first cosmetic brush is customized in size, shape, and stiffness to facilitate the application and blending of a first compound across a first zone on a user's skin. A second brush is customized in size, shape, and stiffness to facilitate the application and blending of a second compound across a second zone on a user's skin. A third brush is customized for applying and blending a third compound across a third zone on a user's skin; and so forth.

Providing an applicator system 10 that includes a systematic correlation between each compound, each zone, and each brush may provide valuable assistance to users of makeup, especially those who are not trained makeup artists. This systematic correlation may be provided to the user, for example, in a set of printed or electronic instructions. By way of example only, the applicator system 10 may provide the following correlations between and among an exemplary set of compounds, zones and brushes, as summarized in the table below and in FIG. 4A-4H.

COMPOUND ZONE BRUSH Liquid Foundation Any or all zones. The Liquidator 220A Powder Foundation Any or all zones. Powder Foundation Brush 220B Concealer Under-Eye Zone 310C Under-Eye Concealer Brush 220C Eye Shadow Upper Eyelid Zone 310D Upper Eyelid Shadow Brush 220D Blush “S Zone” 310E Blush Blaster 220E Decorative Any or all zones. Disco Shine Brush 220F Bronzer Any or all zones. The Bronzer 220G Other combinations of compounds, zones, and brushes will come to mind to those of skill in the relevant field who have the benefit of the teachings presented in this description and the associated drawings.

Exemplary Method of Applying a Plurality of Cosmetics

The systems for applying cosmetics described above may be utilized in a method of applying a plurality of cosmetics to a user's skin. In some embodiments, the provider of one or more components of a system for applying cosmetics may execute the steps in the method. In some embodiments, the user of such a system may execute the steps in the method.

A method in some embodiments may include the step of providing a motorized brush support 102, such as the one illustrated in FIGS. 2A-2H and described above. The motorized brush support 102 may include a handle 104, a motor 113, a head assembly 112, and a coupling assembly 132 configured for releasably receiving a first cosmetic brush. Another step may include identifying or otherwise designating at least a first zone within a surface area on the body, such as the face, to receive a cosmetic.

Another step may include designing and/or collecting or otherwise providing a set of cosmetic brushes 220, such as the set illustrated in FIGS. 2B-2H. This step may include providing a first cosmetic brush, which may be customized in size, shape, stiffness, and other parameters to facilitate distribution of the first compound across the first zone of the surface area to receive makeup. The provider of one or more components of a system for applying cosmetics, in some embodiments, may execute one or more additional steps that are designed to provide guidance and direction to a user. For example, another step may include directing a user to select the first cosmetic brush and mount it to the coupling assembly 132 on the handheld tool 100. Another step may include directing a user to deposit a first particular cosmetic onto the first zone. This step may be accomplished, for example, by using a cotton swab, a foam wedge, a finger, or the like, to collect the first compound from its container and deposit it onto the first zone in a desired amount. The user may also use the first cosmetic brush to accomplish this step.

Another step may include directing a user to distribute the first compound across the first zone by manipulating the handheld tool 100 against the first zone of the surface. This step may be accomplished, for example, by activating the switch 111 (FIGS. 5A-5G) on the handheld tool 100 to start the motor 113, which begins rotating the first cosmetic brush, and by pressing the brush against the areas on the first zone where the first compound has been deposited in discrete amounts (by hand or wedge, for example). In a spreading motion, the user may distribute the first compound as desired; preferably, blending the discrete deposits of first compound across the first zone in order to create an evenly blended layer. The tool 100 and first cosmetic brush may be manipulated in a spreading motion toward and into relatively minute features of the face, such as pores, furrows, creases, wrinkles, and the like. Also, the tool 100 and first cosmetic brush may be manipulated in a spreading motion toward and into the natural features of the face such as those in and around the nose, including the bridge, dorsum, lateral surfaces, alae nasi, alar furrows, nasal septum, and the philtrum. In this aspect, the rotating first cosmetic brush in some embodiments may be manipulated in order to produce: (1) an apparently even distribution of the first compound across the first zone; and, (2) an apparently even and gradually decreasing layer of the first compound around the perimeter of the first zone (for example, along the edge of the first zone, such as along the neck, at the hairline, near the lips, near the eyes, and the like).

In a further aspect, the method may include the steps of identifying a second zone within a surface area on the body, providing a second cosmetic brush customized in size, shape, and stiffness to facilitate distribution of a second compound across the second zone, and directing a user to deposit and then distribute the second compound across the second zone. Similarly, the method may include identifying a third zone, providing a third brush, and directing a user to distribute a third compound; and so forth, for any number of zones.

The method of applying one or more cosmetics, as described, may result in a more efficient application of the various compounds to the area. In other words, the method may accomplish a desired result while using less makeup than other methods, such as application with manual tools and other techniques. In this aspect, however, the even distribution that may be accomplished by using the method may, in practice, result in the application of more makeup and better coverage on certain areas of the body or face.

Also, the method of applying one or more cosmetics, as described, may be more efficient in terms of the amount of manual effort required. In this aspect, for some users, the rotating applicator may accomplish the desired result with less hand and wrist movement than generally required for manual application techniques. The method may be particularly helpful for those with physical limitations due to age, disability, or mobility limitations.

In some embodiments, the user of a system for applying one or more cosmetics may execute the steps in a method, as described above, including the steps of identifying zones, selecting and mounting brushes, depositing compounds, and manipulating a tool to distribute the compounds. The steps described herein, of course, need not be performed in any particular order and may be repeated, removed and re-applied, or otherwise accomplished in any manner to achieve a desired result.

Exemplary Method with Correlation of Compound, Zone, and Brush

In an exemplary embodiment, a method of applying one or more cosmetics may include the step of selecting a surface area on the body to receive cosmetics; for example, the face. Another step may include identifying a first zone within the area, such as the cheeks or “S Zone” 310E and the forehead or “T Zone” 320, as shown in FIG. 3. Another step may include selecting a first compound, such as a liquid or cream foundation, for application to the first zone. In some embodiments, for the provider of one or more components of a system for applying cosmetics, another step may include designing and/or collecting or otherwise providing a first cosmetic brush, such as the Liquidator Brush 220A, shown in FIG. 2B, for use in applying the first compound across the first zone. The Liquidator Brush 220A, in some embodiments, may be relatively large in size, flat across the end of the bristles, and relatively rigid in stiffness. Another step may include selecting and mounting the Liquidator Brush 220A to the coupling assembly 132 of the handheld applicator assembly 100. Another step may include depositing the liquid or cream foundation, using the fingers or a foam wedge for example, in discrete amounts across the cheeks and forehead (i.e., the first zone). Another step may include manipulating the handheld applicator assembly 100 against the cheeks and forehead by pressing the Liquidator Brush 220A against the areas where the liquid or cream foundation has been deposited.
